Abstract

[PROBLEMS] To suddenly shake a vehicle such as an aircraft or a large shake at an earthquake in a high-rise building has a risk of suddenly changing a cart or furniture for serving into a weapon. There are few measures to deal with this, such as trolleys and furniture, and people are rarely but at great risk.
A substrate in which a large number of needles are obliquely implanted and integrated is provided on the bottom surface of furniture or a caster together with a mechanism in which the needles are optionally inserted into a carpet on the floor surface. In the case of a trolley that is fixed to the surface and used for laying aircraft, etc., damage is caused by turbulent airflow by operating the mechanism instantly manually or automatically before the shaking becomes serious and dangerous.

Description

  The present invention is on the floor surface of a vehicle that travels with passengers such as passenger planes, passenger ships, trains, buses, on the floor surface of a high-rise building that shakes greatly when an earthquake is amplified, and on the floor surface that sways. The present invention relates to a fixing device that fixes a trolley or furniture to a carpet on a floor surface and a method for preventing the trolley or furniture from causing a dangerous movement including a movement such as lifting when a large shaking occurs.

  Various methods for fixing the carriage are put to practical use. Protrusion on the underside of the caster so that it is easy to run on the carpet and still prevents falling. When the caster is lifted, the wheel will not touch the outer surface of the caster and stop rotating. There are many things that try to fix the caster to prevent it from moving or falling when it is stopped, such as those that have a fall prevention stopper that can be stored in the caster.

  There is also a method of inflating the tube laterally with compressed air to fix the carriage on the platform of the swaying vehicle, which may be used with the seat on which the passenger sits as a support wall. Another way of thinking is to lay rails on the floor and slide the guides inside to prevent them from vibrating.

  There is also an idea of using magnets for changing the trajectory on which the carriage runs, here there is an excellent method based on the idea of using magnets for the carriage, and if this is developed, it can approach the solution There is sex.

  There is an example that seems to be able to be deployed in a cart, where the wheels are wound around a belt and fixed. This is to push the wheels of the vehicle loaded on the carriage with a belt. This is greatly conscious of the vertical vibration.

  There is an idea to fix the carriage to the floor by stepping on the swinging stopper pipe, and to fix the carriage by pressing the ground friction member against the floor. Furthermore, the idea of moving the carriage with a guide rail placed on the floor and biting into the guide rail results in the function of fixing the carriage from vibration.

  There is also an idea of using a carpet in which a fixing device using hook-like engagement elements is adsorbed on the floor on which the carpet is laid, and a rope or net is hung to prevent collapse of the load. These were all excellent and provided sufficient functions for each purpose, and were practically sufficient.

  However, all the inventions are on the floor of a vehicle that travels with passengers, passenger ships, trains, buses, etc., on the floor of a high-rise building that shakes greatly when an earthquake occurs, and on the floor In order to prevent dangerous movements such as lifting when trolleys and furniture are shaken in the vertical and horizontal directions, it is not considered to be fixed to the carpet on the floor, and the fixing function is insufficient. Met.

  Services that transport food and drinks to passengers' seats that are used to move passengers play an important role in making travel enjoyable, and their importance is increasing ing. On the other hand, however, these vehicles always have the potential to suddenly encounter major shakes during service. Even in high-rise buildings, the possibility of suddenly encountering a large shake is infrequent.

  Taking a passenger aircraft as an example, there are unexpected unexpected turbulences, sudden rises and falls to avoid near misses, and unavoidable sudden driving operations to avoid contact with other cars even on the bus Sudden braking, climbing of fallen objects on the road, passage of uneven parts of the road, etc. are the causes of large shaking. In a ship, when the car shakes in bad weather, the cart may fall over or run on its own.

  Passenger aircraft are becoming larger and larger, but in the case of a heavy aircraft, the amplitude of shaking increases even when encountering the same turbulence. In addition, since the length of the airframe increases, the distance from the center of gravity, which is the center of shaking, increases overall, so that the vertical movement is increased. Furthermore, because the ceiling is high and wide, the distance of the person who jumps up and the distance of movement increases, which also increases the damage.

  Turbulence may be predicted from barometric arrangements and satellite images, and may be based on information from other airplanes flying on the same route, but turbulence of dry air in clear sky with no clouds ( (Hereinafter referred to as turbulence) cannot be seen on satellite images, it cannot be seen on aircraft radar, and the position of turbulence moves over time in the same route. There is always a small low pressure that does not appear in the weather map, vortices that can be formed at the boundary of the front and jet stream, and there are times when turbulence cannot be predicted when there is no information from other aircraft flying immediately before the same route.

  A device called a wind profiler has been developed to detect the wind direction and speed of the sky by emitting radio waves, but this can only be understood around the land where it is installed.

  In the midst of such problems, the aircraft itself has been increasing in size and technology, and at the same time, there has always been an effort to predict the movement of air that causes this significant shaking. However, it has not been possible to completely avoid the sudden trembling that is encountered without predicting it. When this big shaking occurs, the person who is not wearing the belt will be lifted and jumped to the ceiling, leading to a severe cervical fracture, but the damage at that time will be limited to that person alone.

  On the other hand, the hand cart service cart (hereinafter referred to as the cart) that is not contained in the storage unit (hereinafter referred to as galley) in the plane jumps up, moves up and down, and falls. It causes damage to many people. Although there is a recognition that the cart can be a weapon against humans in this way, it is based on common sense that it is impossible to fix this on the side of the cart and solve the problem, I was praised to think.

  For example, partial turbulence at sea is not reflected in the radar, there is no information from the ground, and it is impossible to predict completely even if other methods are added. Large unpredictable tremors occur in a form that is inevitable but less frequent. When crossing the Pacific Ocean on a great circle course, there is a high possibility of crossing with the jet stream, and it is said that the vortex at the boundary will always encounter a few times.

  If you look carefully at the information, damage caused by sudden tremors occurs about once every month on the Pacific Ocean. But not as much as a big accident like a crash. Considering the overall magnitude of the damage, this is a problem that must be taken seriously, and the current situation is focused on improving prediction technology. On the other hand, the cart should consider measures, but there was no focus on it and no method was considered.

  An example of the accident situation is introduced in FIG. This is a record of an accident where United Airlines Boeing 747 (374 passengers, 19 crew members) encountered turbulence over the Pacific Ocean at midnight on December 28, 1997. Looking at this picture, there is a trace (reference numeral 1) that the jumped cart broke through the ceiling. Passengers fell down on the cart that broke through the ceiling and fell down.

  Reprint part of the story. "The people who finished the dessert were in the blossoms of their travel destination. Then the aircraft suddenly started to shake little by little. The shaking gradually increased and the aircraft suddenly drove down rapidly. A cup or plate splattered from the stewardess who was collecting the dishes.The whole body floated in the air as if everyone were descending on a roller coaster.A person sitting on the other side of the aisle I jumped down the aisle and fell down on the document, blood turned red with blood.The cart that was carrying the dishes floated in the air and bounced back from the ceiling, and the customer was lying underneath and fell down. The woman sitting in the seat did not move while being thrown into the aisle.When an ophthalmologist from Chiba rushed to the non-moving customer, she was bleeding from the ears and nose and continued artificial respiration and heart massage, but no reaction No, I had already died because of an intracranial hemorrhage when I hit my head against the ceiling. ”One person died in this accident, 129 severely injured, 10 hospitalized, and 2 of them were paralyzed in the extremities due to a clash on the ceiling Inability to walk.

  From this story, you can read the change in G caused by up and down shaking. G, which is close to 0G, which is weightless, and minus G are frequently applied, and at least once approaches minus 1G. This agrees well with the content of FIG. 2, which is a graph showing changes in G in other accident examples. Here, it begins to oscillate at reference numeral 2, while it swings up and down at intervals of about 2 minutes, there is a large decrease in G at reference numeral 3 after about 20 minutes, and further, at reference numeral 4 after 6 minutes, the value is close to 0G. In this case, it seems that it was a negative G at the rear of the aircraft.

  The route and altitude are specified to prevent accidents between aircraft. On the other hand, the movement of air is free. This is the reason why turbulence can be encountered, but even with unexpected unexpected turbulence among them, current technology cannot completely avoid it.

  The rise of a person in a story can be prevented by wearing a belt at all times. But we don't currently have a way to prevent the cart from rising.

  Measures against sudden turbulence encounters are more focused on the accuracy of the prediction, and it is included in vehicles called aircraft that it is impossible to fix the cart if a sudden large shake occurs. It is accepted that this is one of the overall risks, and there is no interest in the cart measures.

  On the other hand, buses and other vehicles are also increasing in size and improving service. In this case, sudden braking suddenly occurs unpredictably, so the need for countermeasures is the same.

  In a ship's passenger ship, shaking caused by bad weather is easy to predict but unavoidable, and the problem here is that normal service is performed even in that state.

  In the case of high-rise buildings, the vertical movement and roll of the earthquake are amplified and increased according to the floor. At this time, tables, desks, and other platforms run around, causing harm to people and breaking through glass walls. The need for measures to stop this is also the same.

  There are many cases where passengers and crew are injured when passenger planes encounter unpredictable turbulence. In order to understand the size of the problem, the following examples are given. First, on March 5, 1966, British Airways Flight 911 encountered a mountain wave on Mt. Fuji and decomposed in the air, crashed near Tarobo on the hillside of Mt. Fuji, and killed 124 people. Because this is in the clear sky without clouds, you can not see the mountain wave that is the vortex of the air that can be formed after the air flow hits the mountain, and you entered into the turbulent air flow without predicting it It is. Although the existence of mountain waves is now well known, there are still examples of encounters.

  Even if it does not lead to a crash after that, there are no examples of sudden turbulence. December 28, 1997 Late midnight United Airlines encountered turbulence on the North Pacific Ocean and one injured 129 people were hit by the ceiling and died. At this time, the ceiling is destroyed by the cart that jumps up as shown in Photo 1 cited from Non-Patent Document 3. This content has already been described as (Accident Example 1).

  There are many records of accidents that can be obtained, and the list of accidents that occurred in and out of Japan or damaged by Japanese among accidents that encountered turbulence that could not have been foreseen will be as follows. Since these are related to Japan, many are on the Pacific Ocean, but this frequency is an amount that cannot be even more indifferent to the world.

The typhoon was approaching, but it was so high that it was not affected, so there was no sign of wearing a belt. Suddenly there was a big shake.
(Accident Case 17) October 7, 2008 Qantas Airways Flight 72 was involved in intense turbulence over the Indian Ocean and injured 36 people.
(Accident example 18) At 11:45 on February 20, 2009, Northwest Airlines was involved in turbulence at 9200 meters near Miyakejima, and 47 passengers were injured. This was immediately after the sign for wearing the seat belt.
(Accident Case 19) Early April 24, 2009 Canadian Airlines was injured by turbulence over 100 miles south of Honolulu.

  It is surprising that there are many cases just by arranging records of turbulent accidents. Most of these are turbulent air that the captain did not foresee, such as no belt wearing sign and being in the catering. Many of the accidents caused people and objects to jump up to the ceiling. An example in which the cart is destroying the ceiling is shown in Photo 1, but there are many cart accidents that do not cause the ceiling to break.

  Sunny turbulence, especially turbulence over the ocean, cannot be seen from the ground, from satellites, or from the radar of the aircraft. It suddenly encounters without prediction in an unpredictable way.

  Passengers can wear seat belts even when they are calm to prevent their bodies from floating when encountering turbulence. However, it is impossible to prevent the flight attendant who is moving the cart and the cart from rising.

  According to the records of the accident, there was a large up and down movement after a small vibration when there was no sign of belt wearing. At this time, the aircraft is piercing the invisible front, the vortex created by the boundary of the jet stream, or the polar updraft or downdraft larger than the plane.

  When the aircraft enters an ascending or descending airflow region that is larger than the aircraft, the aircraft greatly changes its altitude at that border, and at the same time, the maneuver reacts and changes its attitude to maintain the altitude. Many are autopilot reactions. When the altitude falls, the nose is raised to return to the original altitude. When the altitude goes up, the reaction is reversed. This change in posture affects more than the altitude changes, and causes the front and rear to move up and down around the center of gravity of the aircraft.

  When entering the downdraft, the aircraft moves upwards and changes its attitude, so the rear of the aircraft moves further downward than the aircraft falls, and the G reduction is greater than the G reduction received by the center of gravity of the aircraft. Minus G. This enlargement is greater the further away from the center of gravity. At the front part of the aircraft, the G first decreases, and then the positive G increases. At the front part of the fuselage, the G becomes more relaxed than the G received by the fuselage. This means that in the cabin behind the center of gravity, there is a greater vertical movement than the vertical movement felt by the Captain. This is larger the farther from the center of gravity. When the air enters the updraft, the movement is the opposite, but the movement expands depending on the position in the cabin.

  FIG. 2 is an example of the G sensor records that remained in the fly and recorder in the accident, but it can be understood well that a large shake comes after a small vibration. This is an example in which the shaking time is particularly long, but when viewed here, there are about 10 drops that show a value close to 0 G in 30 minutes.

  This value close to 0G is that of the place where the instrument is placed, and the place is placed in the cockpit which is the front part of the fuselage, and the location of the guest room located behind the center of gravity near the main wing is Because it swings even more than the front of the aircraft, when the value is close to 0G in the record of Fig. 2, it becomes G on the minus side that moves objects upward in the cabin, and people and objects seem to have fallen toward the ceiling at this time .

  The “cart that falls toward the ceiling”, that is, the cart that has jumped up and the cabin crew that was moving by pushing the cart, will fall onto the passenger next when minus G disappears. To make it worse, this is repeated. In this case, even if the passenger wears a belt, it is inevitable that a square metal box close to 50 kg will fall at the place.

  Sudden big shaking is caused by unavoidable sudden maneuvering in addition to turbulence. Usually, a passenger plane flies a route determined by the rules of instrument flight. This means that the westward route is the following integer times 1000 ft, ie 2, 4, 6, 8, 10, 12, 14 16, 18, 20, 22, 24, 26, 28, 31, 35, 39, 43, 47 1,000 ft, the eastward route is determined as 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 33, 37, 41, 45,000 ft Then, the altitude is specified in the flight according to the control instructions. This altitude is a value indicated by the barometric altimeter regardless of changes in barometric pressure. Therefore, all passenger planes are flying in corridors made up of several layers above and below the same fixed route, so they are safe.

  But there are exceptions. Until it rises to this predetermined altitude, the passenger plane must cross the altitude of the other route. This is an unavoidable nature of the aircraft. For this reason, the control is controlled by detailed instructions, but near errors due to human error or the like can occur when making complex intersections. At that time, a sudden maneuvering must occur.

  As with the attitude control when encountering turbulence, ascent and descent in the near miss is performed by changing the angle of the aircraft by raising or lowering the nose around the center of gravity, the change in G in the cabin increases Or larger than the change in G of the aircraft that occurs during the descent. In particular, in a large aircraft with a long body, many guest rooms are far away from the center of gravity, so the value of G applied to the separated guest rooms is larger than the G of the aircraft rising or descending. Therefore, a minus G such that the cart penetrates the ceiling easily occurs.

  An aircraft is a moving object that floats in the atmosphere, and the objects in it and passengers in it are riding on the floor with a downward 1G and moving at a constant speed in the atmosphere. . The atmosphere is not always calm, and if the aircraft body moves up and down due to atmospheric influences, the objects moving inside and the movement of the aircraft will be different and will contact each other. There is a problem that this atmospheric movement cannot be completely predicted by current technology. As such, there are still problems in the immediate vicinity of aircraft, and passenger aircraft are now operating with small risks at all times.

  This issue is being addressed seriously by aviation officials, but it focuses on how to predict turbulence and prevent near misses. Even so, improving the cart and improving safety as a countermeasure against the effects of a major shake as a possible accident is completely overlooked. This is thought to be due to the fact that there was no means.

  Looking at the prior art, it is clear that there is little interest in this problem. That is, although there are inventions that approximate the problem that the present invention aims at, there are no documents that understand the problem and focus on solving the problem. Patent literatures that capture similar themes are as follows. There are many non-patent documents showing the dangers of aircraft, but none of them point out this problem. The following were chosen from among them.

Abandoned by Kanichiro Kato, publisher Kodansha Near Miss, Kanichiro Kato, Kodansha Plane crash due to turbulence http://buturit.dec.cc/essays/hikokijiko/hikokijiko.htm Long-period ground motion, Nihon Keizai Shimbun July 3, 2009 evening edition Long-period ground motion risk map, Japan Architecture Disaster Prevention Association

  In these patent documents, the instability of a moving cart can be attributed to the caster being fixed, the frictional object touching the floor, the rail that cannot be placed on the floor of the cabin, or the chair being pressed against a chair. It is an invention that has a function against the danger of a normal carriage, but it is intended to be done by fixing it with a chair by inflating the tube, which is dangerous if there are human feet or hands there, No consideration has been given to providing a sense of comfort and security and securing them safely.

  Non-Patent Documents 1 to 3 show many dangers that passenger aircraft are potentially possessed. In addition, the dangers in high-rise buildings are generally known through newspaper information. In Non-Patent Documents 4 to 5, it is predicted that the seismic wave with a period of 3 seconds will shake the 30-story building, and the swing will be amplified more than 5 times in the Kanto Plain, and the width of the top floor will be 2-3 m. There is an urgent need to prevent damage to heavy materials.

  The problem to be solved by the present invention is that there is no way to prevent a person from harming humans due to abnormal movement of furniture and carts at such times when a large shake occurs in a high-rise building during an earthquake. thing. In the vehicle on which the passenger rides, when the cabin crew performs the catering service, the cart is moved in anticipation of no shaking, but sometimes it may encounter shaking with up and down movement beyond prediction that can not be predicted, When you suddenly encounter an abnormal G or feel a danger, you want to fix the cart on the floor on the spot, but you can't. There are times when you want to fix the cart to the floor even on buses and passenger ships. Also, to do these things, you can't do it with equipment that does not make people feel uneasy, at first glance, with a normal smooth floor surface. Also, there are times when you want to fix furniture and trolleys anywhere, but there is no way.

  The present invention begins by recognizing an aircraft problem. When a passenger plane encounters a large shake, the cart is usually stored in the galley in advance. However, if you encounter an unpredictable tremor while the cart is moving, it will be difficult to move to the galley, and you will be in danger until you store it, and it will be safe to return to the galley and store it. There is no way.

  There are times when you want to fix the carriage to the floor even on buses and passenger ships, and you want to fix the furniture to the carpet floor even in high-rise buildings.

  When an aircraft encounters sudden turbulence, it is in great danger until the cart is stored in the galley. In such a case, I would like to fix the cart once on the spot until the shake subsides, but I thought it was impossible and necessary. It seems that it was given up as a dream that could not be realized even if it was recognized, and was not considered.

  Furthermore, there is currently no way to deal with sudden swings that are too large to move the cart. Furthermore, even if it is not a large shake, the cabin crew may feel anxious about the expansion of the shake. At this time, I would like to have a safeguard.

  Not only instantaneous response to sudden large shaking, but also operation in combination with the brake in advance when the swing is predicted, and also operation to fix to the floor using the brake when stopping the cart normally If it can be performed, the safety level is further increased.

  In addition, the G sensor is attached to the cart, and when the abnormal G is felt, the fixing device is automatically operated, or the cart is equipped with a wireless receiver and a device that operates in response to the command. If the G sensor analyzes the shaking and determines that it is dangerous, a method may be used in which commands are issued to all carts to operate the fixing device.

  The present inventor has experience of falling 2000 meters by encountering a turbulent flow of mountain waves by his control. While the aircraft was falling, all objects that were not fixed inside the aircraft bounced and moved. Also, while boarding a passenger aircraft as a passenger, there was a sudden shaking, and the cabin crew who was in the vicinity was unable to move the cart and helped to panic.

  This experience seems to have focused on this issue. In the process of that consideration, research was carried out by embedding rails under the floor, laying a thin iron plate under the carpet, attaching a magnet to the cart, fixing it to the legs of the chair, and using strings and wires. However, there was a problem with both.

  Passengers in the cabin must be easy for passengers to walk. In the idea of using rails, foreign objects are present in the passage and it is difficult for passengers to walk, and the floor made of honeycomb for weight reduction is not suitable for strength to embed and lay rails, In addition, the cart with a guide inserted into it has a problem of reduced freedom of movement.

  In the method of using a fixed magnet under the cart, an iron plate must be laid under the carpet, resulting in a problem of increasing the weight of the aircraft, and magnetic force on the passenger's body and property. I was worried about the impact.

  We also considered how to attach an air bag to the side of the seat of the cart and inflate it when necessary to fix the cart to the seat, but the width of the aisle may change by removing and moving the seat and changing the arrangement, etc. Also, considering the danger of passengers' feet and hands on the outer surface of the seat when the airbag spreads, it was impossible to implement.

  The biggest problem was that putting a special feature on the cart that made it stand out made the passengers feel uneasy. In other words, it is not conspicuous and is required to operate instantaneously at any time and anytime.

  The present invention begins with the idea that, after such thinking, the carpet used in the passenger aircraft is a carpet whose upper surface is connected in a loop shape and can be used. If a large number of needle-like objects are pulled onto the loop-shaped thread from above, the eye is fixed to the floor surface and prevented from moving upward.

  The floor of the passenger plane is made of a lightweight material such as a honeycomb, and the carpet is laid on top for the purpose of protecting it from local loads such as sharp heels. The carpet is not usually a cut pile type carpet in which the cut surface of the thread 5 is shown on the upper surface as shown in FIG. 3, but a loop pile type carpet in which the upper surface is rounded in a loop shape as shown in FIG. It is. The fact that this loop pile type carpet is used comes from the necessity of serving as a cart caster who wants to make it easier to roll.

  In some cases, this loop may be partially cut to produce a cut surface of the yarn to be patterned, but this is also a loop-type carpet. A carpet in which the upper surface of the weft yarn knitted by undulation is cut as shown in the cross-sectional photographs of FIGS. The airliner is used to lighten the rolling of the car when the cart moves, and in principle, this carpet is used. The focus on the use of this carpet produced the present invention.

As shown in the structural diagram of FIG. 4, the cross-sectional photograph of FIG. 5, and the schematic diagram of FIG. 6, the pile yarn rolled into a loop shape as indicated by reference numeral 6 (hereinafter referred to as loop yarn) can hook a needle from the upper surface, The strength of one loop of pile yarns bundled to a diameter of about 1 mm is about 3 kg, and there are about 1000 in 100 cm @ 2. On the other hand, the bending strength of the needle exceeds 3 kg with one 0.8 mm diameter cotton needle. In other words, if half of the 100 needles are hanging on the carpet loop pile yarn, the weight of 150 kg is supported.
If you cut the loop partly and make a pattern, the pile thread that works in the loop will work. It is also possible to reach the needles to the hemp cloth.

  Normally, the direction of the loop of the carpet on the floor of the passenger plane is the same on the entire floor of the aircraft. In this case, the direction in which the needle is hooked may be one direction in the front-rear direction or the lateral direction of the airframe, and it is preferable to align the direction in which the needle is inserted in a direction perpendicular to the loop direction.

  The loop yarn is twisted as shown in FIG. 4 and the pile is tightly sewn into the fabric such as hemp in the same direction. However, since the twist is twisted, the direction of the upper surface may not be determined. Again, the needle pierced in a certain direction captures the pile loop. Still further, fixing is performed even when trying on a cut pile type carpet having no loop on the upper surface. This is effective even though the effect is inferior to that used for loop carpets, whether the needles are inserted between the twisted fibers or between the tight seeps, or the needles reach the fabric.

  Adhesion between the carpet and the floor of the honeycomb is often double-sided adhesive tape, but the vertical peel strength is about 35 kg / 100 cm2, which is also sufficient considering the area of the bottom of the cart. have. If the number of needles is increased and placed in a large area, the strength will function more sufficiently

  With this strength as a background, a method for fixing the cart was completed by hooking a large number of needles onto the dense fibers of the carpet, mainly the loop yarns that make up the carpet, when necessary.

  There are various surface conditions of the carpet, but if the loop direction is vertical or horizontal, or irregular, it is desirable to pierce the needle in two directions or multiple directions. The case where the loop yarns are neatly arranged will be described. The pile yarn is twisted so that the direction of the loop is not aligned correctly, but the slanted needles also catch the fibers and loops well.

  The needle may be a cotton needle, a dedicated needle or a nail, or it may be straight or bent (hereinafter collectively referred to as the needle body). It is preferable that the hook has a shape that does not easily cause damage, and the hooking method that does not easily cause damage is preferable. However, in the case of a method that can reduce the number of times of hooking, this damage does not need to be emphasized.

  Also, in the case of usage with high insertion frequency, take a method of reducing friction on the surface of the needle body in order to reduce damage to the carpet caused by piercing the needle body, do not apply force even when piercing, aramid fiber ( It is also effective to mix high-strength fibers such as (trade name) into carpets.

  An example of a plate (hereinafter referred to as a needle plate) planted by using a 0.8 mm diameter cotton needle with the needle body tilted from the substrate is shown in the photograph with the needle body of FIG. In this, the needle body of 8 is obliquely arranged on the substrate of 7 and fixed with resin. However, holes may be arranged in the base and the needle body may be inserted and fixed, or the needle bodies may be arranged and fixed. It may be integrally formed by injection molding. FIG. 8 shows a schematic diagram of the needle plate with the needle body facing down.

  The rising angle from this substrate has an optimum angle depending on its usage. It is between 10 and 45 degrees, and the angle can be increased if the lateral movement force is kept strong. In this case, there is a feature that the vertical movement can be increased. When it is desired to increase the vertical fixing force, it is preferable to reduce the angle.

  The cart presses the outer periphery of the wheel of the caster and uses it as a brake to stop. Even if the brake is stopped and the needle body is inserted into the carpet, if no negative G is applied, no force is applied to the loop yarn of the carpet, and the damage to the loop yarn is very small. Therefore, if you feel uneasy about shaking even if there is no shaking, it is a good safety and security measure to activate the device and insert the needle. This is an advantage over the manual case. When it is safe, release it manually and move the cart.

  In the case of automatic operation, when the data change of the G sensor predicts danger, the operation command of the device is issued, and if it returns to 1G, the cart will not be able to move during this operation. To avoid danger. Therefore, it is preferable to use a mechanism that also applies the brake. Since the present invention is an invention of a mechanism for fixing a cart to a floor surface using a needle body, in order to do this, the apparatus is operated by predicting danger by analyzing directly from a G meter signal or entering a computer. The description of the electric circuit is omitted.

  If the operation of the device is delayed and the cart has already been lifted, the needle piercing will be lost. In this case, should the device be restarted promptly the next time it touches the floor? Continue operation.

  When the needle plate is located under the cart with the needle body on the bottom and away from the carpet, when a large shake occurs, or when a shake is predicted and a danger is felt, or when it is stopped Then, the needle plate is pressed against the carpet surface and shifted laterally in the direction of the needle tip, or is moved obliquely into the direction of inserting the needle body, and the needle body is hooked on the carpet loop. This movement is shown in FIG. Further, the moving needle plate and the bottom surface of the cart are structured so as not to release the cart upward when the cart is lifted upward.

  There are various shapes of the needle plate to be inserted into the carpet as shown in FIG. It is a method of using a pair of needle plates so that the needle piercing direction is reversed and sandwiching them from opposite directions as indicated by reference symbol a, spreading them in the opposite direction as indicated by reference symbol d, or arranging them as shown by reference symbols b and c. . Alternatively, the lateral movement of the needle plate is set to one direction, and one of the needle plates is a holding plate having a needle body vertically or not having a needle body, and the needle body is inclined only from one direction as indicated by reference numerals g, h, and i. It is also possible to puncture the needle body in a concentric sequence as shown by the symbol e, and to plant the needle body by tilting it in the concentric direction and rotating it.

  FIG. 11 shows a method of planting a needle body on the substrate denoted by reference numeral 7 and the shape of the needle body. Although the symbol a is a standard shape, it is better to use the symbol b · f according to the movement of the needle plate. In some cases, the symbol c is a case where the needle body is planted perpendicularly to the surface of the substrate and then bent, and the symbol d is a case where the needle body is fixed without being stabbed into the substrate.

  FIG. 12 is a method of making a needle plate by a method different from the method of inserting the needle body into the substrate of reference numeral 7. The steel plate is cut and molded into the shape of reference numeral 9 with a laser, and this is attached to the substrate. At first, we used the established manufacturing technique of cotton needles, but we should choose a method that suits our purpose.

  The needle plate is usually exposed on the bottom of the cart that is not touched by people who are not visible to the human eye, but is exposed when it falls or floats in the air if it fails to be fixed. It is dangerous against. This is a case where fixing should not fail, but FIG. 13 is for the safety in that case. Symbol a in FIG. 13 does not sharpen the tip of the needle body of symbol 11 like b. In the case of a loop carpet that is rounded as indicated by reference numeral 12, the shape of the tip of the needle body is sufficiently stuck in the carpet. Ordinarily, there is a method such as symbol c in which the needle body is hidden in the hidden plate 13 and the tip of the needle body comes out when it contacts the floor surface.

  There are two types of carpets: Wilson carpets, where pile yarns are passed from below to hemp fabrics, and patquet carpets that are stabbed from above. In either case, the pile yarn is connected at the beginning and the upper surface is connected in a loop. Cut pile carpets are made by cutting the top of the loop immediately after planting on the fabric. Generally, a pile yarn is fixed by applying glue on the back of the fabric. In the industry, what is connected in the form of a loop is called a loop-pile type carpet. A cut-pile type carpet that has the upper surface cut and the surface is aligned, and a pattern that is partially cut from the upper surface is loop-and-looped. Although it is called a cut-type carpet, it has been described here mainly for a carpet with a loop.

  In the present invention, it is a requirement that the floor surface is carpeted, the floor surface is preferably the floor surface of the loop carpet, and exhibits the most performance in the loop carpet, but not related to the loop carpet. It is.

  In the case of a loop carpet, when the needle body is not inserted into all the adjacent loops, one loop is pulled, and the pile thread of the adjacent loop connected to the thread is shifted and dragged, and the pulled loop is In order not to stretch, it is desirable to fix the pile yarn by applying glue on the backside of the fabric.

  As described above, as a means for solving the problem, the passenger aircraft with the most prominent problems has been described. This means is common to the floors of high-rise buildings that shake greatly and all other floors that shake. In carts that move on moving vehicles, they operate when there is a risk of shaking, and in order to prevent building furniture from moving abnormally in an earthquake and causing harm to people, It is attached to the floor surface and fixed to the floor surface, both of which fix the trolley and furniture to the floor surface carpet by inserting the needle body on the needle plate attached to the trolley and furniture to the floor surface carpet. Is the most important feature.

  A cart or furniture having a needle plate on which a large number of needle bodies are obliquely fixed according to the present invention is inserted into a carpet loop or dense fiber when the cart or furniture is subjected to abnormal vibration. It is fixed to the floor surface. This prevents the cart or furniture from moving in the vertical direction or the horizontal direction, and prevents the cart or furniture from becoming a weapon and harming people. Furthermore, there is a great advantage that the person who handles this can use it with peace of mind.

  The furniture or cart used on the floor, which is expected to have large vertical or horizontal vibrations, is expected to detect or detect abnormal movements before the large vibrations. The needle of the needle plate attached to is inserted into the carpet and fixed, or the needle of the needle plate attached to the cart is inserted into the carpet immediately before. The mechanism is simple and securely inserts the needles of the needle plate into the carpet loops or dense fibers to secure the furniture or trolley safely.

  FIG. 7 is a photograph of an embodiment of a throat plate that is the basis of the device of the present invention. The needle used for this was a cotton needle with a diameter of 0.8 mm, and 153 pieces were arranged on a 100 × 200 mm aluminum plate substrate (reference numeral 7) at an angle of 15 degrees and solidified by pouring an epoxy resin on it. It is.

  This needle plate only needs to have a large number of diagonal needles in parallel, and a large number of diagonal holes may be made in the substrate, and needles may be inserted into the substrate and fixed. It is also possible to form a single piece by providing a melted resin after the needle is inserted into the needle.

  A prototype made of a nail with a diameter of 1 mm was a good result, but the one used as a cotton needle had a lower resistance to puncture, and the carpet did not leave a mark even after repeated punctures.

  FIG. 14 is manufactured as an example of the present invention for earthquake countermeasures for high-rise buildings. It has a needle plate shape indicated by a symbol e in FIG. Reference numeral 18 is a needle plate in which an angle-shaped fixing tool 14 is fixed to a furniture leg or a side surface of a furniture by a mounting hole 15 and several rows of needles are planted obliquely in a concentric direction on the lower surface of a circular board 7. Is placed on the carpet and rotated clockwise to insert it into the carpet. Next, the nut 16 is pressed downward, and the nut 17 is fixed to the fixture.

  The fixing device of the second embodiment is used for furniture that does not move, and the similar fixing tool of the embodiment of FIG. 15 is used for a carriage, furniture with a space on the lower surface, or the like. In this case, when the circular needle plate (reference numeral 18) is rotated clockwise toward the lower carpet, the rough thread of the bolt that supports it pushes out the length necessary to pierce the needle. In the case of furniture after being fixed to the carpet, it may be fixed with a nut. In the case of a trolley, a rotating device capable of normal rotation and reverse rotation may be attached to the fixture.

  The embodiment of FIG. 16 is also a method of rotating the needle plate, but was completed for the cart. Even if the vertical movement of the aircraft is strong and the cart rises, it continues to rotate until the carpet is grasped. It is a method that can be.

  As an operation instruction, the coaxial wire 19 is loosened and the slip motor 20 is switched on at the same time. The support bar of reference numeral 22 pulled downward by the spring of reference numeral 21 is lowered, and the circular needle plate of reference numeral 18 starts to rotate clockwise by the gears of reference numerals 23 and 24. The needle plate continues to rotate while being pushed down by the spring indicated by reference numeral 26 until it is stopped by the stopper indicated by reference numeral 27. When the cart is in contact with the floor and the needle plate 18 is engaged with the carpet, the rotation of the needle plate is stopped by the slip motor, and the fixing of the cart to the carpet is completed.

  In the case of a cart, it is necessary to immediately release the cart and return to the galley and store it after the aircraft has finished shaking. In order to perform a quick release, the slip motor is reversely rotated at the same time that the coaxial wire 19 is pulled. When the throat plate of reference numeral 18 is detached from the carpet and the support screw of reference numeral 25 pulled upward by the support bar of reference numeral 22 is engaged, the throat plate of reference numeral 18 is further raised and stopped. In this state, the process returns to waiting for the next operation instruction.

  The embodiment shown in FIGS. 17 to 20 has a needle plate shape indicated by reference sign a in FIG. 10 and has a mechanism for piercing the carpet by the movement indicated by reference sign c in FIG. In FIGS. 18 and 19, the width of the throat plate is expressed to be small in order to make the structure easy to understand. 17 will be described with reference to the schematic diagram of FIG. 17 and the reference numerals of FIGS. FIG. 20 depicts the operating state of the mechanism shown in the schematic diagram of FIG. 17, and the contents are the same as those in FIG.

  In this embodiment, the slide plate of the reference numeral 29 is fixed to the bottom plate or the bottom mounting plate of the reference numeral 35 with a fixture having a triangular or trapezoidal side shape of the reference numeral 28, and the same as the needle plate. The needle is pierced by a slider 31 which is fixed by a fixing tool 30 which is inclined. That is, the needle plate moves by inserting the needle into the carpet by parallel movement.

  It is standard that the inclination of the slide rail 29 is almost the same as the inclination of the needle 11 in the needle plate 18, but it is preferable to change the angle depending on the surface condition of the carpet and caster conditions. In some cases.

  The needle plate 18 is always pulled to the stopper in the direction in which the needle is pulled out by the spring 32. When the toggle clamp of reference numeral 33 is tilted, the needle plate of reference numeral 18 is pulled by the wire of reference numeral 34 via the pulley, and moves downward in the direction of insertion. The needle must not touch the carpet at the time of normal arrangement, and the needle is inserted from the high position. Therefore, the length of the slide rail is large so that the slider moves on the slide rail.

  In the case of the prototype, the length of the needle is 14 mm, the inclination is 20 degrees, the slide rail angle is 20 degrees, the moving distance of the slider is 30 mm, the vertical movement by the operation is 12 mm, The distance to the carpet was 9 mm, the depth of penetration into the carpet was about 3 mm, and the carpet using the loop carpet was not in contact with the carpet in normal times, and the fixing during operation was good.

  If the toggle clamp shown in FIG. 17 is moved to the upper part of the cart by extending the wire, it can be used in a normal cart. It may be operated without using a toggle clamp and placing a special ratchet mechanism petal next to the stepping brake petal. In addition, there is also a method of automatically performing the release manually. In any case, whether it is manual operation, stepping operation or automatic depends on how it is used, and it is better to choose it accordingly.

  The embodiment shown in FIG. 21 has a needle plate shape indicated by reference numeral c in FIG. 10, and has a mechanism for piercing the carpet by the movement indicated by reference numeral b in FIG. In this embodiment, the needle plate hollow bar 36 has a square shape, and the needle plate hollow bar 37 slides while maintaining the same surface.

  This hydraulic pressure is sent by a hydraulic pump with a stepping petal of reference numeral 43. The six marks 50 attached to the cylinder in FIG. 21 indicate the connecting portions of the oil pipe, and the pipe is omitted. This movement can be performed not only by hydraulic pressure but also by a combination of a coaxial wire and a spring or by electric drive.

  The embodiment shown in FIG. 22 has a needle plate shape indicated by reference numeral b in FIG. 10, and has a mechanism for piercing the carpet by the movement indicated by reference numeral d in FIG. In this embodiment, the movement of the crank is used, and the needle is lowered along the arc by the link 44.

  The needle plate 18 is raised approximately 45 degrees by the spring 45, and when it is stepped on the petal 46, it is pulled down by the wire 47. In this case, a ratchet is provided on the axis 48, and the needle is stopped in accordance with the situation where the carpet is caught. Reference numeral 49 denotes a ratchet release string.

  The embodiment shown in FIG. 23 is of a simple mechanism that pierces the carpet with the movement indicated by reference numeral c in FIG. It is comprised by the hydraulic pump of the code | symbol 43, and the hydraulic cylinder of the code | symbol 39 attached diagonally. While this mechanism is simple, it exerts an oblique force on the hydraulic cylinder when a load is applied, which increases the size of the hydraulic cylinder. 6 marks of the reference numeral 50 attached to the cylinder in the figure indicate connecting portions of the oil pipe, and the oil pipe is not shown.

  In the embodiment shown in FIG. 24, in order to make the movement of piercing the carpet with the movement indicated by the symbol d in FIG. The method of inflating the balloon 51 with the air pressure taken from the cylinder is the simplest, although it cannot be used repeatedly.

  By using a needle plate that embeds many needles at an angle and stabs the needle diagonally downward into the carpet, the cart, carriage, and furniture that fix the needle plate are fixed to the floor and have large vibrations. Protected from. It is effective as an earthquake countermeasure for high-rise buildings, and if this mechanism is attached to a cart such as a passenger aircraft and operated in response to shaking, it will be much safer against turbulence accidents. Although it is a blind spot of the current technology and there is no specific requirement, the potential demand greatly contributes to safety. It leads to industrially effective results.
